Would "I use it at work" count? :)

I don't think so. My initial thoughts would be perhaps carpentry but a knife of that size wouldn't be suitable for anything, and it would presumably be carried around as part of a toolkit and not as an individual item. I also think it's incredibly naive of you to imply that the majority of people carrying knives are "using them for work", unless "work" to you means being a paid hitman or some other kind of thing which I'm sure you aren't involved with.

My boyfriend Fred wears two knives at work every day! Sometimes even a machete when working with
Did he ever hurt anyone? Yes, himself! Big scar on the left hand! Knives kill people! The human beings are innocent, people!
